    Ecology: Adults are commonly known as 'demoiselles'.
    Instream habitat: Neurobasis australis occurs in lotic waters. Australasian Neurobasis species are found amongst gravel and rocks in clear, fast flowing creeks, streams and rivers, mostly within forested areas
    Feeding ecology: Nymphs are predators.
    Life history: Australasian Neurobasis males are territorial and defend potential oviposition sites. Females usually lay their eggs on submerged floating root mats or plants, usually at a depth of 5-15 cm below the water surface.
